Application filed September 17'. 191:2. Serial No. $330,869.

To all.' tir/Atom it: may 'conne/'n Be it known that We, CLARENCE H. lloiw Ano and HARRY M, Prenom, citizens of the United States, residing at St. Louis, ldis-l souri, have invented a certain, new and use- ;t'ul lini'iroveinent in Car-' rneks. ot' which the following is a full, clear, and exact description, such 'will enable others skilled in the art to which, it appertains to malte and use the saine, reference being had to the accompanying drawings, forming part of this speeilieation, in which- Figure l is a top plan View of a four-- Wheel truck oi our improved construction. Fig'. 2 is a Vertical, longitudinal section taken approximately on the line 2-42 el? Fig. l. Fig. 3 is a'transverse section taken approximately on the line 3-2-3 of Fig. l.

l'ig. #t is a detail section showing a modified forni of the swing hanger that supports the spring plank and truck holster.

(Jur invention relates generally to izn proved ear trnelts of the four-Wheel variety, and particularly to a trnele designed especially for use heneatl'i loeonioti-te tenders.

lhe principal feature ot' our :improved eonetrnetion is the swing hangers utilized lior Supporting the springA plank and parts carried lliereby., which swing hangers have tivopoint supports, or points ot' pivotal eonneotion (pre'li'erahly at their upper ends). the ohjeet ot which twopoint support is to render said hangers comparatively rigid against lateral ,swinging movement under normal conditions so that on a straight track haring' an occasional low joint or other low part thaty might cause the tender body to swing or shift laterally, no swinging movement will be produced, but when the eentritng'al force is abnormal, as in rounding curves, the swing hangers will then swing laterally, and, by reason of their two-point suspension, the centrifugal 4force will he ahsorhed and utilized as a lifting force for elevating the tender body.

To the ahove plu-pos( our invention consists in certain novel features et' construel'ion and arrangement of parts hereinafter more fully described and claimed.

Referring by numerals to the accompanying drawings l designates the Wheel pieces and L) the transoms of the truck frame, said pieces l and transoins 2 parte being;n prellerahly east iiiiteerai eo as to provide an especially strong. rigid and @omn paratively cheap structure. wheel :fire preiteralily shape in cross seetion with suitable gusset plates in the corners between the transoins and wheel pieces. fllhe end portions of the transonis are made substantially narrower than the central. portions. suoli. construction being Carried ont. inenting tionsl ol the vertical walls of said transoinr close to each other, thereby 'oririing com para-tively narrow housin, s Ytor the opper portions of swing` linkes hereinafter de scribed.

Formed in the vertically disposed wel) i'ilates or walls ot` the transoms 2 and near the ends thereof are pairs of horimntallj;y disiiiosed bearings 3 in which areY seated short, horizontally disposed pins or bolts d.

The spring plank swing hanger links i are provided in their upper ends with short, vertieally disposed pairs ot slots (l. through. which pass the pins or bolts fl. Thus a pair ot spring1 plank swing hangers i5 arranged adjacent to each wheel piece oit' the trnelr lli-aine, and said swing hangers being pivot-- all;v supported at their npper'ends at two points.
